Which of the following is a negative risk factor for coronary artery disease?

The correct response highlights that an HDL (high-density lipoprotein) value of greater than or equal to 60 mg/dL is considered a negative risk factor for coronary artery disease. HDL cholesterol is often referred to as "good" cholesterol because it helps transport cholesterol from other parts of the body back to the liver, where it can be processed and removed from the body. Higher levels of HDL are associated with a lower risk of heart disease because they facilitate this protective mechanism.

In contrast, lower HDL levels (like those under 40 mg/dL) are linked to an increased risk of heart disease due to insufficient cholesterol transport, which is why they are not viewed favorably. Possible elevated LDL levels and prediabetes are also indicative of higher risk factors rather than protective mechanisms against coronary artery disease. Therefore, having a high HDL level serves as a beneficial factor in cardiovascular health, making it a negative risk factor for coronary artery disease.
